20mm GM20-20BY: 18° Step Angle Geared Stepper Motor (2 Phase 4 Wire) for Optical Equipment
The PM20 reduction stepper motor stands out for its enhanced precision: after integrating the reduction gearbox, step angles are subdivided to boost load torque and control accuracy. Choose from reduction ratios (10, 12.5, 25...488) to match your speed/precision needs, paired with 5V-12V operation and speeds spanning 10rpm-500rpm. At 20mm in diameter (18mm motor length, 16.0mm-20.5mm gearbox lengths), it’s lightweight yet durable—motor life exceeds 10,000 hours, gears 2,000+ hours—perfect for lab instruments and automated test stations.
